Solar water pumps are self-contained systems powered by solar photovoltaic (PV) modules and a pump inverter. These pumps utilize sunlight to generate electrical power (DC) through the PV modules. This DC power is then fed to the pump inverter, which converts it into AC power to drive centrifugal mono-block or submersible pump sets, extracting water from bore wells, open wells, or reservoirs.
The system is designed to operate efficiently with varying power inputs, producing different water outputs depending on the time of day—typically yielding higher output in the afternoon and lower in the mornings and evenings. It features an automatic start and stop function, requiring no user intervention. The entire setup is straightforward and robust, offering years of maintenance-free operation. Most importantly, solar water pumps can be installed anywhere, regardless of proximity to the electrical grid, since sunlight is widely available and free of charge.
